Hi List I'm using PGSEA and I would like to plot the results of my analysis using the smcPlot function in the package. Using this function appends a row labelled 'GS' at the bottom of the plot. I would like to use custom row labels for my plot and have created a vector of names as suggested in the package documentation. When I try to use this I get the following error: Error in axis(4, 1:nrow(m), las = 2, line = -0.5, tick = 0, labels = rnames, : 'at' and 'labels' lengths differ, 52 != 51 suggesting that my rnames vector and the number of rows in the matrix used for the plot have different lengths. They don't however - both are 51. The 'GS' not in the matrix before it goes into the plotting function (smcPlot) and I can't see anything indicating that this is added in the plotting function. I've also tried adding a 'dummy' label to my vector of row labels (i.e. to make it 52 in length) but the result is the same. Could anyone enlighten me?
